Why do modules with circulating flow have particularly poor elasticity after convergence?
Thread Content
During the simulation, I noticed that once my simulation with a circulating flow pattern converged, it would no longer converge even after making slight changes; I’m not sure why
The convergence range of simulations with circulating flow patterns is inherently small, making them more sensitive to operating conditions; what the original poster described is normal
1# superyj: If the process is relatively long, it should be set to Tear Steam; minor components should be suppressed during convergence, and the convergence tolerance can be set a bit higher.
An initial value can be set for the circulating flow rate, which facilitates convergence
